2U Rackmount Fanless Micro-ATX Case for Intel® Core™ (Ultra) Processors with Fanless ATX Power Supply
2U rack-mountable fanless case for Micro-ATX motherboards with 150W fanless ATX PSU. Supports processors up to 35W TDP with Intel® LGA1851/LGA1700 sockets. Features 4 front 2.5" SATA SSD/HDD hot-swap drive bays and 4 rear low-profile PCIe slots. Perfect for industrial server, control, telecommunication or broadcasting systems.
Designed to support a diverse range of common Micro-ATX and Mini-ITX form factor boards with Intel® LGA1851/LGA1700 sockets.
Supports Intel® Core™ (12th/13th/14th Gen) & Core™ Ultra (15th Gen) processors up to 35W TDP.
High-performance aluminium thermal module and dual copper heatpipes transfer heat efficiently from the CPU to the external aluminium fins, increasing surface area for rapid dissipation into the surrounding air without any moving parts.
Features USB 3.2 Gen 1 (5 Gbps) Type-A ports and low-profile PCIe slots for expanded connectivity.
2U profile height, rackmount case with convenient pull-out handlebars. Fits in standard 19" server racks.
Perfect for enterprise server, embedded computing, industrial control, audiovisual, medical equipment, or NAS/RAID applications.
Supports up to four 2.5" SATA SSDs/HDDs (up to 9.5mm height) with designated, lockable, tray front flaps for easy, tool-less mounting with hot-swap capabilities.
Completely fanless design eliminates noise and reduces mechanical failure points, ensuring reliability under continuous operation.
Ideal for applications sensitive to sound and vibrations.
Supports up to four low-profile PCIe cards.
Delivers 150W of power with completely fanless, convection cooling for silent operation.
Space-saving 198.0 x 97.0 x 40.5 mm (D x W x H) form factor with thermally conductive 1U chassis for efficient passive heat dissipation.
Performs reliably from -10°C to 70°C.
Operates from 90 to 264 VAC, compatible with power systems worldwide.
Provides standard ATX voltage outputs (+3.3V, +5V, +5V standby, +12V, -12V) for broad system compatibility.
Achieves up to 83% efficiency at typical load, reducing energy waste and heat output.
Class D active power factor correction (PFC) improves power quality and reduces harmonic distortion
Meets EMI EN 55022 Class B standards, delivering interference-free operation in home, office or other sensitive electronics environments.
Features Over Voltage (OVP), Over Temperature (OTP) and Short Circuit (SCP) protections to protect both the PSU and connected components.
Meets international ITE safety standards including:
Equipped with ATX 24-pin main connector, 4+4-pin CPU and SATA power connectors.
Available with a mains plug power cord, with EU, UK and US options currently offered. Other plug types may be available upon request.
